L14 tripped regularly throughout shift. Early in shift L14, L15,L21, R24 were all at 3800V. After L14 was identified as the culprit of the once-per-minute trip rate its voltage was lowered to 3750V while the others were raised to 3850V. This brought the trip frequency within tolerable limits.

Also noticed some stranged behaviour of HVGUI where general crate trips occurred but WC's themselves were not tripping. Reset rectified this but we could not determine which channel actually tripped. This happened twice.

Latter half of shift was plagued with variabel beam quality and many bad fills.

All crunchign caught up.
